    I just took a few pics of a skywarp custom and the purple looks blue in the pics (purple paint and LEDs). I tried a different camera and got the same result. I also tried every setting in the cameras. I used a Canon Ixus 105 and an old Kodak easyshare.

    I've seen a lot of skywarps and shockwaves on here that look purple. Whats the trick?

    Yeah, I have the same problem too. Assuming you turn off the camara light, the external lighting play a big role too especially in indoor, florescent vs. incandescent. But I noticed if I photographed outdoor with a nice natural light from the sun, the purple looks very close to the object I'm photographing. But then again, if all fail, I used Photoshop to edit the purple hue.

    Try adjusting the settings for light / ev compensation, also try adjusting your brightness, contrast and color saturation settings. Ideally you want to raise saturation and brightness a notch or two, and lower contrast by half a notch (or leave it alone).

    End of the day, try those settings, see what makes the quality better, and adjust as necessary. Just keep a note of what the last "good" setting was so you can revert back if necessary.

    i agree 1000%
    I had the same problem, not only w/ purple, but all colors. (Luckily at the time photoshop's "auto color" would put them true to life)

    at 09 TFcon Solscud gave me a quick run down on camera light settings. I have mine now set to "Tungsten" which is dead on (most of the time)

    Another important factor is your monitor....make sure it's decent. If your monitor shows a purple in a certain way which it is not - you might open a can of worms.

    Thanks guys.

    I've literally tried every setting and combination on the camera, I'll try some different lightng conditions tomorrow. I'm taking the pics indoors under those eco globes, I have 3 different color temps, I also used high powered leds as the light source and a normal incandescant globe. I've tried with and without the lightbox.

    My monitor is calibrated.

    All other colors are spot on.

    I've been trying to correct them in paint.net but it takes forever and looks shit. I need to get photoshop.

    After all the rooting around I did to get the right shade of purple this shits me. I should have just painted him red and made it purple in photoshop :)

    I just thought I'd interject here with Adobe Photoshop. One of the things I typically do when I get a gallery of my photos is import the gallery into Photoshop and do three things to all photos (in this order too, via hot keys):

    1. Auto Contrast [Alt+Ctrl+Shift+L]
    2. Auto Levels [Ctrl+Shift+L]
    3. Auto Color [Ctrl+Shift+B]
    4. Save As for Web [Alt+Ctrl+Shift+S]
    5. Close Window [Ctrl+W]
    6. Repeat until finished with the gallery

    I can buzz through 50-75 photos in about 10-15 minutes doing this, especially if I get a really good rhythm going. Hot Keys FTW :)

    dude, you so need to learn how to batch edit then. You can save that list as an "action" then apply ALL those edits to ALL photos in a specific folder...in seconds...

    Batch edit in Photoshop? You could have replied with the directions on how to do it.

    Actions're really the only thing I miss from Photoshop. Need to double-check to see if GIMP has anything similar...

    Speaking of, a little GIMP trick that might help the original poster adjust one color~

    We'll use the blue>purple conversion since it's the main topic. I'm using Mirage, who's supposed to be blue, but he'll do for example's sake. Lazy picture is lazy, by the by.

    [​IMG]

    Then once the pictures up, go up to your toolbar and click:

    Colors > Hue-Saturation...

    And you'll end up with a window like this.

    [​IMG]

    Click on the "B" radio button so this only affects blue shades. Now adjust the hue to the right to get something a bit more purple.

    Aaand you should end up with something like this.

    [​IMG]

    My purple Mirage's looking a little spotty, but that has more to do with the original quality of the pic and less with the actual color conversion.

    Now, you may need to use your lasso or magic wand tool to grab the offending purple-blue while leaving any true blue intact, but otherwise, the process is the same. There should be a similar option in Photoshop, I'm sure. But GIMP's free, and a much smaller download. Available for Windows here.
